Dear KuCoin API Users,

In order to improve the performance of KuCoin Futures API, KuCoin will carry out a live upgrade at 07:00 (UTC) on February 9, 2026. The upgrade is expected to last 120 minutes. During the upgrade, the Classic Futures WebSocket feed may experience disconnections, latency, or data loss.

If there is significant market volatility prior to the upgrade, we will postpone the upgrade based on market conditions and make an announcement accordingly.
